Figure 6.

Permeability to FITC-conjugated albumin in rats treated with saline or 400 mg/ml tiron daily over a course of 5 days. Data from rats mechanically ventilated for 2 hours at 25 ml/kg Vt and zero positive end-expiratory pressure at a frequency of 35 breaths/min under isoflurane are compared with spontaneously breathing rats. Data are expressed as mean ± SEM of BAL/serum fluorescence ratio fold change above spontaneously breathing rats. *P < 0.05 versus spontaneously breathing rats; ^†P < 0.05 versus saline-treated mechanically ventilated rats.
